Chameleon by Joana e Carlos Rondão

You can choose to start as red (default) or if you prefer blue, there's an option for that too. Your goal is to cover all the board with pieces of the color you chose. You can move up to two squares in any direction - move just one and you replicate your piece. After the move all opponent pieces adjacent to your piece will turn your color. Move two and your chosen piece will teleport to the square you choose instead of duplicating.
Only 0.5 MB, with animations, option to have random blocks, different difficulty levels with strong AI, Chameleon is a mentally challenging game good to pass time and challenge yourself.
